Quoting @FrederikBolding:

To support hardware wallets as snaps we can expose WebHID and WebUSB via globals. However, we would need to initialize the hardware connection in the MetaMask extension by allowing the user to click a button, triggering a user gesture outside of a snap. After that is done the connection should be available to snaps.

This is the same way the extension is currently doing it. While we are still running snaps in iframes, this seems like the only option.

Can we emulate WebHID and WebUSB in Node.js?
